IMPROVEMENT IN COTTON-PICKERS.

Specification forming part of Letters Patent No. 53,44 7, dated March27, 1866.

To all whom it may concern:

Be it known that I, GEORGE A. HOWE, of the city ofBrooklyn, in the Stateof New York, have inven ted certain new and useful Im provements inCotton-Harvesting Machines; and I do hereby declare that the followingis a full and exact description of the same, reference being had to theaccompanyingdrawings, and the letters of reference marked thereon.

My invention consists in an improvement in strippers for detachingcotton from an endless rotating toothed chain or gatherer in handcotton-harvesters, and is also applicable to any machine which operateson the same general principles.

In the accompanying drawings, Figure l represents a vertical andlongitudinal section of a cotton-harvester. Fig. 2 is a view of myimproved stripper, in perspective, showing a part of the endless toothedchain passing around its axis.

To enable others skilled in the art to make and use my improvement, I.will proceed to describe ils construction and operation.

A A AA is the external case ot a cotton-harvester. B is the central partof the stripper, and a b c cl @fits fans or wings.

C C is the endless toothed chain, which is made to revolve on the axisof the stripper B and on the rollersg and m. This chain is rotated bymeans of the gear h meshing into the chain O. The gear h revolves upon ashaft connected with a standard, which is secured to the under part ofthe case A.

k is a hand-crank operating the gear h. D is the point in the toothedchain where it seizes the cotton, which is conveyed by the chain pastthe roller g to the stripper, by which it is detached from the chain anddelivered from the machine through an opening at E in the exterior case,A.

The stripper has two sets of fans, as shown in Fig. 2, one set operatingon each side ofthe chain. Those parts of the strippers shaft to whichthe fans are attached are cylindrical and have a diameter greater thanthat of the central part, around which the chain turns, and the fans areattached to the shaft as tangents thereto.

lt has been demonstrated by experiment that a fan-stripper having thefans arranged in relation to the shaft or axis in the form ot' radii,and operatingin connection with an endless belt or chain of the generalcharacter here represented, frequently fails to perform the partassigned' to it, and this failure results in clogging the stripper andinterruliting the operation of the machine. The tangential arrangementof the fans, as shown in my improvement., successful ly prevents thiscloggin g, the fans lifting and detaching the cotton from the chainbefore it reaches the shaft of the stripper.

I do not claim the application of a fan or fans to a gathering-chain asa means of removing the gathered cotton from such chain; but

NVhat I do claim as my invention, and desire to secure by LettersPatent, is-

The arrangement-of stripper-fans in respect to thel shaft onwhich theyrevolve as tangents thereto, substantially as described.
